Officials also found 54 gun-style lighters in hand luggage at Australia's major international airports.

"Screening requirements at airports are in place to ensure the safety and security of the travelling public," federal Infrastructure Minister Anthony Albanese said.

"Items that can't be part of your carry-on baggage include things like weapons, replica weapons, explosive or high flammable goods and items including sporting or household goods that could be used to threaten, harm or restrain someone.

"If you are not sure whether an item is prohibited, check with your airline, pack it in your checked baggage or leave it at home."
